Searching with OpenSearch

OpenSearch is used as a tool for searching and analyzing data in documents through:

• Structured queries similar to SQL queries: to find documents with a set of fields that meet the specified conditions.
• Full-text queries: to find a certain string in the documents and sort the results by relevance. These queries also allow you to use additional search functions, including autocomplete and search for phrases and similar strings. To learn more about full-text search, see the OpenSearch documentation.
• Complex queries that combine the above types of queries.

In Managed Service for OpenSearch, you can run queries of all these types using pre-installed search plugins, such as Querqy, SQL and PPL, and more.

Search features in OpenSearch include the following:

• You can run search within a specific index in a cluster or across multiple indexes.
• Asynchronous search is supported for large queries that may take a long time to run.

To learn more about search options, see the OpenSearch documentation.
